DISPENSING RESERVOIR.

Application led December 27, 1921. Serial No. 524,908.

This invention relates to an apparatus used for dispensing liquid fuel in measured quantities, and has special reference to the specific arrangement of pipes used for mtroducing the liquid into the transparent vessel or reservoir used for measuring.

In order to more clearly describe my 1nvention, I shall have reference to the accompanying drawing f1n which the single view shows my improved transparent measuring reservoir.

Numeral 1 represents the top of ,a sheet iron 'casing which is Lused to support the transparent reservoir 2, and also to enclose the valves and piping of my apparatus, which, however, isv not shown 1n this drawing. Reservoir 2 is preferably a cylindrical glass vessel secured to a metal bottom, not shown, and provided with an ornamental cap 3. The liquid fuel enters the reservoir through pipe 4 whose topis provided wlth a cap 5. Directly beneath the lower edge of cap 5 I provide a number of holes 6 through which the liquid leaves the pipe. In order to prevent splashing of the liquid as it enters the reservoir throughv holes 6, and to cause the liquid to reach the bottom of the reservoir in a quite and orderly manner, I enclose the upper end of minum tube `7-whose inslde diameter is considerably greater than the outside diameter of pipe 4;- this'tubehas the upper end closed as indicated by numeral 8, which closure is provided with a vent 9. YTube 7 is held in place by means ofa screw 10, which has screw threaded engagement with cap 5. An overliowI pipe 11 41s also provided.

From the above it will appear that I have provided means whereby the liquid will enter the reservoir at the top, but in such amanner that it will resent theappearance of entering near the ottom. The holes 6 in the top of supply pipe 4 are above the level of the top of the overliow pipe 11, and as the aluminum tube 7 has a vent 9, it is obvious that no si honing action can take place when the liqui in pipe 4 recedes, as it sometimes will. By my arrangement of pipes, the liquid will enter :the reservoir quletly and without the formation of violent waves, as is the case -1 where it enters directly at the bottom through a pipe. Y However, the mainfeature of my improvement is the delivery of the liquid to the. container @inthe top and above the top 'o f ipe 4 with an alu-V the overiow pipe 11. In "constructions of this class, the top of the oveiow pipe determines the level of the li uid`\in the container whenl the latter is ful, andin order to secure the full benefit and advantage of the invention, it is necessary that the opening or openings at the top of the inlet pipe 4, through which the liquid enters the container, shall be above the top of the overflow pipe 11,or at least as highas the top of said overfiow pipe, since the main object of the invention is to prevent 'the possibility of the escape of the llquid in the container through the inlet or lilling pi e 4. IVhere a different construction is emp oyed, that is, where the liquid is delivered to the container at the bottom throu h a pipe whose upper end 1s at or near t e bottom of the container or terminates at -any point 'below the top of the overflpw pi it is lnecessary to use a check valve in t e inlet pipe to revent the return of the liquid to the s ree of supply after the force, as -air pressure, which causes the .liquid to enter the container, ceases to act. But itis found in actual practice, or in the use of dispensers of this character, that where valves are employed for this urpose, it is impossible to prevent them rom leaking, and to the extent that leaks occur, a part of the liquid in the container is returned to the supply tank and there is a consequent loss to the customer or purchaser. In lother words, if the container holds ten gallons, the top of .the overflow pipe is so located as` -to retain this amount therein, and for obvious reasons an excess is always delivered which is taken care of by the overow pipe. But if the open end of the inlet or filling pipe is below the top of the overflow pipe, and

Vil() there `is a leaky check valve in the inlet pipe, a' part of the ten gallons which the customer should receive will leak back into the supply tank before the contents of the container can be lowered to the open end of the inlet pipe, `and the farther the de let pipe Whether or not there is a valve therein, and conse uently there 'is no neces-` sity for a check va ve in this pipe.

Hence, the real object of the invention set forth in this application is to prevent loss to the customer by leakage from the container through the inlet pipe after the container is lilledu Having now described my invention, what I claim as my invention or discover is:

l. In a liquid dispenser, the combmation with a container having an overflow pipe terminating in the upper portion thereof, of na supply pipe extending upwardly into the container, and having its ioutlet opening at lleast as high as thetop of the overflow pipe, and a housing enclosing said supply pipe, said housing being opened at the bottom and having a vent opening in.y its` top.

2. In combination, a reservoir adapted to vcontain a liquid, a supply pipefor conducting said liquid into sa1d reservoir, said pipe extending upwardly to a point near the top of said reservoir, an opening near the top of said pipe, and means for conducting the vliquid downwardly, comprising a tubular member having its upper end "closed, said,

tubular member enclosing said pipe, and a vent in the upper end of said tubular member.

3. In combination, a reservoir adapted to contain a liquid, a supply pipe for conducting said liquid into said reservoir, said pipe extending upwardly to a point near the top of said reservoir, a cap on the upper end of said pipe, a plurality of holes in said pipe near the upper end thereof, a tubular member enclosing said pipe, said tubular member having its upper'end closed and pro vided with a vent.

4. In combination, a reservoir adapted to contain a liquid, a supply pipe for conducting said liquid into said reservoir, an overllow pipe having its upper end open, said supply pipe having its upper end closed and top of the overflow pipfe for supplying liquid to the container, such means being vented to prevent the escape of liquid from the container therethrough.

6. In liquid dispensing apparatus, the combination with` a container having an overflow pipe, of a conduit extending above the top of the overflow pipe for supplying liquid to the container, said conduit being vented to prevent the escape of liquid from the container therethrough.

7. In liquid dispensing apparatus, the combination of a container having an overflow pipe, of means located within the container and extending above the bottom thereof for delivering` liquid thereto at a point at least as high as the top of the over` ilow pipeysaid means extending downwardly toward the bottom of the container and being vented'to prevent the escape of liquid from the container therethrough.

8. In liquid dispensingapparatus, the combination of a container having an over- Iflow pipe, of means located within t-he container and extending above the bottom thereof for delivering liquid thereto at a point at least ashigh as the top of the over-
